Cut bell peppers in half crosswise and remove seeds. Slice cucumbers and cut cherry tomatoes in half. In a large mixing bowl, combine the tuna, carrots, and corn, and toss in the mayonnaise or dressing. Spread the spinach leaves evenly on 4-6 small salad plates. Place the bell pepper half on top of the spinach and fill it up with the tuna and vegetable mixture, top with the cucumber and cherry tomato halves.

Cooking Notes

A wonderful variation here is cutting the bell peppers into wide strips and use the tuna salad as a dip.
